Definitions
- This invention relates to gas compositions comprising a fluorine-containing nitrogen compound, which compositions are useful for cleaning the interior of reactors such as chambers for CVD (chemical vapor deposition) processes or etch processes used for manufacturing semiconductor devices on substrates.
- the invention also relates to such gas compositions capable of efficiently etching films of silicon-containing compounds.
- the gas compositions have little or no tendency to generate an effluent gas stream containing noxious ingredients, such as CF 4 , NF 3 and the like.
- WO 99/67817 discloses etching a silicon surface using a gas which comprises at least three reactive gases which include at least one fluorine-containing compound which does not contain silicon, at least one silicon-containing compound, and oxygen.
- US 4,536,252 discloses laser-induced production of nitrosyl fluoride for etching of semiconductor surfaces.
- thin films have been formed by known techniques such as CVD processes.
- CVD processes e.g. a thin film for semiconductor devices within a CVD chamber
- the film-forming material is also deposited, though wastefully, on the remaining surfaces exposed to the interior space of the CVD chamber, including, for example, the surfaces of inner walls of chamber, product-holding jigs, pipings, etc.
- the material which has accumulated on surface areas other than the target area(s) can be accidentally separated therefrom. Consequently, the peeled-off material or particles thereof can often be carried to the target area where a film is being formed or to be formed, and can cause the film to become contaminated therewith. This would prevent the process operation from producing films of satisfactory quality, and thus would lead to decreased yield. Therefore, it is necessary to remove any undesirably deposited material from the chamber at appropriate intervals and clean the chamber. Removal of the obstructive deposits from the interior of CVD chambers has been carried out manually or chemically, by means of cleaning gases.
- the cleaning gas should be able to rapidly clean the interior of the CVD chamber, while the etching gas should be able to selectively and rapidly etch the selected area or areas of deposited film. Further properties commonly required for the cleaning and etching gases include, for example, that they do not generate noxious effluent gases and they are environmentally friendly.
- a class of perfluorocompounds such as CF 4 , C 2 F 6 , SF 6 , NF 3 and the like have been employed in large amounts in the processes for producing semiconductors and other electronic devices, as a gas for either removing the deposited materials or for etching the deposited films.
- these conventional perfluorocompound gases are stable substances that can last for a long period of time in the atmosphere and it is difficult to treat a waste gas stream omitting the cleaning step or the etching step in which the above-mentioned conventional cleaning or etching gases are employed.
- the waste gas stream may contain a high level of the cleaning or etching gas ingredient(s) in an undecomposed or undegraded state and the treatment to reduce these to acceptable levels before discharging to the atmosphere is very expensive.
- fluorine-containing nitrogen compound offers: improved ability to clean deposits comprising silicon-containing compound(s), while generating, during use in a cleaning process, an effluent gas stream containing no noxious compounds, such as CF 4 , NF 3 or the like, that seriously contribute to global warming; also, improved ability to etch a thin film comprising silicon-containing compound(s), while generating, during use in an etching process, an effluent gas stream containing no noxious compounds, such as CF 4 , NF 3 or the like, that seriously contribute to global warming.
- the present invention has been developed and accomplished on the basis of the above finding.
- an object of the invention is to provide a CVD chamber cleaning gas composition which has excellent performance in cleaning deposits comprising silicon-containing compound(s) and, thus, is useful for cleaning the interior of reactors such as chambers for CVD process used for manufacturing semiconductors, and other electronic devices or the like layered on wafer substrates, and which will generate, during use in a cleaning process, an effluent gas stream containing no noxious compounds, such as CF 4 , NF 3 and the like, that seriously contribute to global warming.
- a further object of the invention is to provide an etching gas composition which offers excellent performance in etching films comprising silicon-containing compound(s) for manufacturing semiconductors, and other electronic devices or the like layered on substrates, and which will generate, during use in an etching process, an effluent gas stream containing no noxious compounds, such as CF 4 or the like, that seriously contribute to global warming.

WO 99/67817 -
US 4,536,252 discloses laser-induced production of nitrosyl fluoride for etching of semiconductor surfaces. - To date, in processes for producing thin-film devices, such as for the production of semiconductors, thin films have been formed by known techniques such as CVD processes. In the formation of such a film, e. g. a thin film for semiconductor devices within a CVD chamber, though it is desirable to allow or permit a film-forming material to deposit preferentially over the target area or areas of the wafer substrate or substrates held in the CVD chamber, the film-forming material is also deposited, though wastefully, on the remaining surfaces exposed to the interior space of the CVD chamber, including, for example, the surfaces of inner walls of chamber, product-holding jigs, pipings, etc. Furthermore, during the deposition process, the material which has accumulated on surface areas other than the target area(s) can be accidentally separated therefrom. Consequently, the peeled-off material or particles thereof can often be carried to the target area where a film is being formed or to be formed, and can cause the film to become contaminated therewith. This would prevent the process operation from producing films of satisfactory quality, and thus would lead to decreased yield. Therefore, it is necessary to remove any undesirably deposited material from the chamber at appropriate intervals and clean the chamber. Removal of the obstructive deposits from the interior of CVD chambers has been carried out manually or chemically, by means of cleaning gases.
- In the production of semiconductors and other electronic devices, it is also necessary to partially remove a layer or layers of various semiconductive materials deposited on a wafer substrate by means of an etchant, typically an etching gas, so as to leave a semiconductor circuit in a pre-determined pattern on the wafer substrate.
- Some fundamental properties are generally required for the chamber cleaning gas and the etching gas which both act to remove the materials deposited in the chamber. The cleaning gas should be able to rapidly clean the interior of the CVD chamber, while the etching gas should be able to selectively and rapidly etch the selected area or areas of deposited film. Further properties commonly required for the cleaning and etching gases include, for example, that they do not generate noxious effluent gases and they are environmentally friendly.
- Heretofore, a class of perfluorocompounds, such as CF4, C2F6, SF6, NF3 and the like have been employed in large amounts in the processes for producing semiconductors and other electronic devices, as a gas for either removing the deposited materials or for etching the deposited films.
- However, these conventional perfluorocompound gases are stable substances that can last for a long period of time in the atmosphere and it is difficult to treat a waste gas stream omitting the cleaning step or the etching step in which the above-mentioned conventional cleaning or etching gases are employed. The waste gas stream may contain a high level of the cleaning or etching gas ingredient(s) in an undecomposed or undegraded state and the treatment to reduce these to acceptable levels before discharging to the atmosphere is very expensive. These aforementioned problems have been presented by the conventional cleaning and etching gases. Furthermore, it is known that the conventional perfluorocompound gases have very high global warming potential (ITH; 100 years): when compared with carbon dioxide (CO2), CF4 exhibits a factor 6,500 times; C2F6 exhibits a factor 9,200 times; SF6 exhibits a factor 23,900 times; and NF3 exhibits a factor 8,000 times, respectively, that of CO2. There is a concern that these substances could have a serious effect on the environment.
- Under the circumstances, there has been a strong need for a substitute etching or cleaning gas that has a low global warming potential, one which exhibits excellent performance in cleaning deposits of silicon-containing compounds as well as excellent etching performance for the silicon-containing compound films.
- Even if a gas itself as used in the cleaning or etching process has no or little effect on the environment, the gas could be subject to decomposition during the cleaning or etching process, at the same time generating noxious gases, such as CF4 and NF3, which last for a long period of time in the atmosphere. Therefore, it is desired to provide a substitute etching or cleaning gas that will not decompose to produce any noxious gas or gases having an adverse effect on the environment.
- Thus, the inventors, having focused their efforts on research into the amelioration or elimination of the above-mentioned prior art problems, have now discovered that a particular kind of fluorine-containing nitrogen compound offers: improved ability to clean deposits comprising silicon-containing compound(s), while generating, during use in a cleaning process, an effluent gas stream containing no noxious compounds, such as CF4, NF3 or the like, that seriously contribute to global warming; also, improved ability to etch a thin film comprising silicon-containing compound(s), while generating, during use in an etching process, an effluent gas stream containing no noxious compounds, such as CF4, NF3 or the like, that seriously contribute to global warming.
- The present invention has been developed and accomplished on the basis of the above finding.
- Accordingly, an object of the invention is to provide a CVD chamber cleaning gas composition which has excellent performance in cleaning deposits comprising silicon-containing compound(s) and, thus, is useful for cleaning the interior of reactors such as chambers for CVD process used for manufacturing semiconductors, and other electronic devices or the like layered on wafer substrates, and which will generate, during use in a cleaning process, an effluent gas stream containing no noxious compounds, such as CF4, NF3 and the like, that seriously contribute to global warming.
- A further object of the invention is to provide an etching gas composition which offers excellent performance in etching films comprising silicon-containing compound(s) for manufacturing semiconductors, and other electronic devices or the like layered on substrates, and which will generate, during use in an etching process, an effluent gas stream containing no noxious compounds, such as CF4 or the like, that seriously contribute to global warming.

- The gas composition for cleaning CVD chambers may consist of an inert gas or gases in place of the O2, wherein the content of FNO is desirably in the range of 55-95 mol % per 100 mol % of the total quantity of the gas ingredients in the composition. Desirably, the content of said inert gas or gases is in the range of 5-45 mol %.
- Alternatively, the gas composition for cleaning CVD chambers may consist of an inert gas or gases in addition to the FNO and O2, wherein the content of FNO is desirably in the range of 20-90 mol % per 100 mol % of the total quantity of the gas ingredients in the composition.

- Alternatively, the etching gas composition may have an inert gas or gases in addition to the FNO and O2, wherein the content of FNO is desirably in the range of 20-90 mol % per 100 mol % of the total quantity of the gas ingredients in the composition.

- The CVD chamber cleaning gas compositions according to the invention are listed in the claims. These will be explained below.
- The chamber cleaning gas compositions of the invention are characterized by inclusion of FNO in combination with O2 and/or one or more inert gases.
- In the case where the chamber cleaning gas composition of the invention consists of FNO and O2, the content of FNO is desirably in the range of 20-50 mol %, and preferably 30-45 mol % per 100 mol % of the total quantity of the ingredients in the composition.

- Where the content of FNO, O2 and inert gas(es) used in the chamber cleaning gas compositions falls within the above-mentioned ranges, it is possible to quickly remove the deposits on the surfaces of the interior of the CVD chambers.
- In view of the chemical structure and physical and chemical properties of FNO, it is believed that the compound would have a short lifetime in the atmosphere and contribute less to global warming. Therefore, only a very slight adverse effect on environment would be caused if the chamber cleaning gas compositions were discharged into the atmosphere.
- Further, even when FNO decomposes during use of the cleaning gas composition in the cleaning step, it would emit little or no noxious gases, such as CF4, NF3 and the like, that have high global warming potential and have an adverse effect on the environment.
- Furthermore, since FNO has a low boiling point of -59.9°C, it is present in the gas phase when it is used under the conditions employed in the production of semiconductors and other electronic devices. Therefore, the gaseous FNO or gaseous mixtures containing it may be handled easily in the chamber cleaning operation.
- FNO may be prepared, for example, by the below-formulated route at a high yield rate, but the preparation is not limited thereto:
F2 + 2NO- 2FNO
